Answer:
A = 81 m²
Step-by-step explanation:
The formula for area of the parallelogram is
A = LH where L is the length of the base, and H is the height
L is given as 9, and H is given as 5, so
A = (9)(5) = 45 m²
The are of the triangle is
A = (1/2)bh where b is the base and h is the height
b is given as 9. Its's 9 because that side of the parallelogram is parallel to the base of the parallelogram and is also equal in measure. The height of the triangle is give as 8, so the area is..
A = (1/2)(9)(8)
A = 36 m²
The total area is
45 m² + 36 m² = 81 m²
Answer:
Step-by-step explanation:
third side=√((√73)²-7²)=√(73-49)=√24
So first we want to distribute. (#1)
So, using the distributive property, we can:
5 * 3x - 2y * 5 + 2x + 2 * 2y - 3 * 3x - 3 * 2y
or
15x - 10y + 2x + 4y - 9x - 6y
Now just combine like terms
8x -12y
So for #1 it should be a.
#2: 2x - 3 + 3x - 5
Combine Like Terms:
2x + 3x - 3 - 5
5x - 8
So it should be b.
The value of z is 73.8
Im sorry it is hard to explain
Answer:
400 cm²
Step-by-step explanation:
Triangles: 1/2x15x8=60 (two of those)
Base: 8x7=56
Back: 15x7=105
Sloped side: 7x17=119
60+60+56+105+119=400 cm²
